Mine locked up at a gas station 12 miles from home. Cost me $100 to have it towed home and about 2 hours of my time.
(Actually, it cost me an entire afternoon - but the time to FIX it was abotu 2 hours, but it sure screwed up my saturday!)

Been fine ever since... but you are right, if it's acting funny, GET IT FIXED. We all know these cars do this, certainly most of them, anyway.
